I know next to nothing about the Provocateur or the draconic feats, but I can whip up something that you could at least use for a spring board for ideas. I'm going on the basis that:
- You have bard casting
- You want to primarily focus on fighting
- You want to focus on Diplomacy

Skill points per level: 4. Class Skills: Appraise, Bluff, Concentration, Craft, Diplomacy, Disguise, Gather Information, Intimidate, Knowledge (Arcane), Knowledge (Dungeoneering), Listen, Perform, Profession, Search, Sense Motive, Speak Language, Spellcraft, and Spot.
Class FeaturesWeapon and Armor Proficiency: a <class name> gains no new proficiencies with weapons and armor.
Claws (Ex): A <class name> gains two claw attacks as primary natural attacks that each deal 1d6 points of damage (or 1d4 if small-sized) plus her Strength modifier. She may opt to hold a weapon in one hand and make a claw attack with her off hand at a -5 penalty to hit.
Dragon Scales (Ex): At 1st level, a <class name> becomes more like a dragon. She chooses a dragon type (black, blue, green, red, white, brass, bronze, copper, gold, or silver) and grows scales of the appropriate color. This grants her a +1 enhancement bonus to her natural armor bonus. This bonus increases by +1 every three class levels thereafter. A character without a natural armor bonus is treated as having an effective natural armor bonus of +0.
Energy Adaptation (Ex): The <class name> gains energy resistance equal to her class level + 10. The type of enegy resistance granted is based on the type of dragon she chose for her Dragon Scales ability.

Spellcasting: At 2nd level, the character gains new spells per day as if she had also gained a level in whatever arcane spellcasting class she belonged to before she added the prestige class. She does not, however, gain any other benefit a character of that class would have gained. If a character had more than one arcane spellcasting class before she became a <class name>, she must decide to which class she adds each level of <class name> for the purpose of determining spells per day.
Breath Weapon (Ex): At 2nd level, the <class name> gains a breath weapon that she can use every 1d4 rounds. The breath weapon deals 1d6 points of dmage per
character level, with a Reflex save (DC 10 + 1/2 her character level + her Constitution modifier) for half damage. The shape of the breath weapon and type of energy damage is based on her dragon color:

blue 60' line of electricity
green 30' cone of acid
red 30' cone of fire
white 30' cone of cold
brass 60' line of fire
bronze 60' line of electricity
copper 60' line of acid
gold 30' cone of fire
silver 30' cone of cold

Wings (Ex): At 3rd level, the <class name> grows wings and gains a fly speed equal to twice her base land speed with average maneuverability.
Bite (Ex): At 4th level, the <class name> gains a bite attack as a secondary natural attack (-5 penalty on the attack roll during a full attack). This attack deals 1d8 points of damage (1d6 if small sized) plus half her Strength modifier.
Enlarge Person: At 4th level, the <class name> adds Enlarge Spell to her list of spells known, as a 1st level spell.
Tail (Ex): At 7th level, the <class name> grows a tail, and may use it as a secondary natural attack (-5 penalty on the attack roll during a full attack). This attack deals 1d8 points of damage (1d6 if small) plus half-again her Strength modifier, and is considered a reach weapon. She may attack adjacent creatures with this tail attack without penalty. If the tail hits an opponent, she may make a free trip attempt against the creature and does not risk falling down on a failed attempt.
Draconic Transformation (Ex): At 10th level, the <class name>'s type changes to dragon, and she gains all the appropriate traits. She also gains immunity to her selected energy type. She may still affect herself with her Enlarge Person spell.
AnalysisThis should be relatively tanky and have some good versatility from the casting advancement. You will primarily play as a fighter-type with some extra tricks on the side. The breath weapon deals on okay amount of damage, but can't be used all the time. It's best for dealing with large numbers of weaker opponents. By the time you get wings and at-will flight, you're 8th level, which is almost when casters are using Overland Flight all day long anyway.
