Well, here's one involving only dragonborn and warforged, the SRD, and a single The Mind's Eye article (no flaws). Minimal outside interference, as it were.
Feats
1. Combat Reflexes
1. Hidden Talent (Psionic Minor Creation)
1. Weapon Focus (Soulbound Weapon) - Bonus feat from the Soulbound Weapon ACF
2. Soulbound Weapon ACF
3. Extend Power or Empower Power
5. Psionic Meditation
Powers
1. Psionic Minor Creation
1. Call Weaponry (Good for Extending)
1. Expansion (Good for Extending)
1. Compression (Good for Extending) or another power of your choice (such as Vigor)
2. Dissolving Weapon (GREAT for Empowerment)
2. Strength of My Enemy (Good for Extending)
Cha is a dump-stat, and you don't have a lot of use for Int (especially if you jump into barbarian or martial monk for Improved Trip), though it might be nice for some Craft checks, so don't dump it TOO much, and you only need a marginally decent Wis for this particular build (at least until later on, when you can purchase some Wis-boosters). Dex, Con, and Str are important, though Str can be augmented using the Expansion and Strength of My Enemy powers when needed, and Dex can be boosted (a little) via Compression. You can focus on melee OR ranged, or you can do both, so use that to determine which is more important between Dex and Str.
The fun part here is the fact that you're immune to poison (even being dragonborn -- you don't lose your living construct subtype, which gives you immunity). Use Psionic Minor Creation to coat yourself and your weapons and armor in one or two different kinds of poison, each of which lasts 5 hours for only 1 pp.
Also, you're a living construct and have infinite stamina. You can use those wings to fly without tiring out like most creatures do. Huzzah!
Your standard modus operandi is to rely mainly on poisoning everything you've got on you with a contact poison and using Expansion for some extra melee damage and your off-day manifestations of Dissolving Weapon on your arrows for extra ranged damage. Strength of My Enemy is great as both a buff and a debuff, but it doesn't have that long of a duration, so I wouldn't use it too terribly often (though later on you can use the Persistent Power feat from Hyperconscious to make it last all day long). However, note that it works on both melee and ranged weaponry, so it segues well into both styles, especially if you get yourself an elvencraft bow (from Races of the Wild). Maybe use that for your soulbound weapon, so you have lots of options on when and how to use it. Since you can fly you can definitely snipe from above. Flight + Poison + SoME is a nasty combo, and you can use it well (assuming a decent Dexterity score, anyway).
Empower Power is great for some strong manifestations of Dissolving Weapon on your off-days. Extend is mostly for Strength of My Enemy, since it's cheaper to just remanifest Psionic Minor Creation (and it lasts for 5 hours at a time anyway).
Do make sure you have a pair of spiked gauntlets and a reach weapon (such as a guisarme), though, so when you have Expansion up you can do some battlefield control with your trips. (Remember that dragonborn removes your slam attack). You don't have Improved Trip (though that can be rectified with a couple of levels in barbarian, or a level in martial monk, or even two feats), but you still get a nice hefty bonus from your increased size and strength when using Expansion (and who cares if you provoke AoOs if they can't reach you?). And even without the attack from Improved Trip, you still are covered in contact poison, and the touch attack from the trip attempt will expose your foe to at least one dose.
Choose a versatile weapon type for your soulbound weapon (such as an elvencraft composite longbow). Use it for when you really need JUST the right tool for the job. Fighting a hydra? A temporary sundering weapon is MUCH better than blowing a feat on Improved Sunder. Blowing a +1 on ghost touch sucks, so pop that on your SW when you need it. It's not for everyday use, since it's rather expensive to augment, so only go after it when you'd be screwed without it. Get to know your weapon enhancements and you'd be
amazed at how powerful and versatile this option is.
Alternatively you can go barbarian 2 (grabbing pounce, Improved Trip, and a plethora of other always-on abilities, as well as whirling frenzy or rage) or martial monk 1 or 2 (with Tashalatora, of course, though that's outside of the scope of this particular build-stub). Go for Improved Trip and the Knockdown feat in the SRD (or Deities & Demigods). It'll save you tons of power points, as well as a few feats (though you will have fewer pp and lower level powers available). It's actually a decently worthwhile trade. That and you can have a ton of battlefield control at your draconic robotic fingertips.
From here you can either focus on melee and BFC, or ranged damage and debuffs. Or you can easily split the difference with some clever use of the buffs at your disposal. You've got some excellent powers and versatile feat choices at your disposal, so find ways to make each choice fit into both categories!
Make sure to buy lots of 1st level power stones. According to CPsi (which may or may not be in play at the time of this writing), you can expend your own pp to manifest the power in the stone at your manifester level (which includes augmentation and metapsionics). However, a lot of low-level psywar powers are great at ML 1. Inertial Armor is a good choice, as are Call Weaponry (autoscales due to your ACF), Expansion, Compression & Psionic Minor Creation (all of which are good for emergency manifestations when you actually do run out of power points), Chameleon, Bite of the Wolf (note that this also auto-scales with your psywar level, despite still only having a ML of 1), Synesthete, My Light, Detect Psionics, and Skate. Quite a steal for only 25 gp each, and you can spend your own pp in a pinch to knock the manifester level up as needed.
More expensive but still potentially worthwhile are numerous 2nd level power stones. Body Adjustment (and it's not an effect subject to your warforged 'curse' of half-healing), Energy Adaptation, Psionic Darkvision (mostly for emergency use), and Wall Walker.
I hope this at least sparked some ideas.

Also, karmic strike is good, but it's better for someone with the ability to heal vampirically. Psywars at later levels have a number of options with which to do this, but early on, opening yourself to attacks is much worse than whacking them with a trip-oriented attack of opportunity.
