Feats to aggro

[Telonius]

Not a feat, but a Prestige Class feature: Divine Prankster 5 (from Races of Stone) gives you the "Enrage Enemies" Comedic Performance. The targeted creature must make a Will save or attack the Prankster. The DC is set by a Perform (comedy) check, and skill checks are easy to boost; so this can be a pretty reliable aggro mechanic against creatures subject to it. (It's Enchantment(charm) Mind-Affecting). Do note that it's a spellcasting class, generally intended for Cleric/Bard multiclasses (though other combinations are possible to meet the prereqs).
