I came up with something self made.
A dwarf Fighter 7/ Kensai 2/ Fighter 2
I took the trait that make me one size larger.
I builded my feats around trip/grapple etc and also AoO
I picked up the spiked chain (and made it +5 with speed, thanks to the kensai) and i "Buyed/crafted" a ring of enlarge person.
Any thought on this? I know it's not super optimized or something but, can it work?
I can't get a coherent list of materials allowed enough to make a suggestion. You listed some books at the beginning (which are subject to change, but ToB probably won't make the cut, but who knows, otherwise). Then DnD WiKi somehow sneaks in as allowed source, but only for templates? Oh wait, for traits as well, you meant. Then you crafted a magical ring with a level 9 Fighter/2 Kensai. When you ask does that build work, do you mean does it literally function RAW? Probably not considering what you're trying to craft. Can 9 levels of Fighter and 2 levels of Kensai co-exist? Yes. However Synthetic Soul is for Constructs and Undead only. Is Tasha's Hideous Laughter going to nullify your character? Well, it certainly could, couldn't it?
Edit:
and immunity to magic as trait.
Sorry, I missed that. Oh, great, magic immunity is useful. Tasha's jokes aren't that funny, after all. Taking a second look at your sources allowed, a cleric is probably your best tank possibility, even without Spell Compendium, due to Divine Metamagic even though you don't get access to Magic Item Compendium to boost your turn attempts or expanded Domains to choose from SpC. Druids are good, but I like some of the animals found in other MM's better than MM1. But still, for everything you summon, you are saving the party HP/resources when it takes damage/enemy focus.
Edit 2:
As I read more of your post, I see:
so it's like i will be forced to play warrior (I don't really want to play a cleric).
I have the perfect build for you. This is a little-known uber optimized tank build posted years ago by someone important. Here it is:
Dwarf Fighter 9/Kensai 2
(1) Improved Unarmed Strike
(F1) Combat Expertise
(F2) Improved Trip
(3) Dodge
(F4) Combat Reflexes
(6) Eyes in the Back of Your Head
(F6) Improved Combat Expertise
(F8) Mobility
(9) Elusive Target
(K1) Signature Weapon: Unarmed Strike, Unarmed Strike (+1)
(K2) Power Surge, Unarmed Strike (+1 Flaming)
Okay, so you obviously want feats. Lots of feats. They will carry you through. Position yourself between the enemies and your allies. Use a Tower Shield to maximize your armor class and max your Combat Expertise so you don't get hit. Since Trip attacks are touch attacks, your attack bonus doesn't matter one single bit. Enchant your body with +1 and then Flaming. This is important. +1d6 Fire damage doesn't look like much, but for a fortress, it is essential. Eyes in the Back of Your Head will shut down flanking bonuses which is crucial (another effective +2 or more AC and negates Sneak Attack from proc'ing in that way) and Elusive Target protects you from the extremely common NPC feat Power Attack. Most NPC's are Uber Chargers (missing citation here). With your skill points, make sure you invest heavily in Balance and Climb. Sometimes you might come against a wall and Climb helps or in other cases you might have to balance on a Grease spell or special terrain. This will be such a flaming character. Good luck and I accept Pay Pal.
