Before I continue, I'll echo the previous comments about Hyperconscious- I find it indespensible for Psionics in general- and the Minds Eye stuff. That WotC subsection is worth exploring just for the expansion of the Pyrokinetic PrCl into a suite of PrCls covering each energy type...and there is much more there besides.
At one point, I started a thread that contained all of the WoTC Psionic PrCls that were not in the XPH or Complete Psionic...then came "The Great Kerfluffle" which made a lot of data dissapear- that thread was among the casualties.
While I'm not restarting that here today, I do recall that many post-XPH books would have a hidden psionic PrCl or 2... For instance, there is the Cognition Thief in Forgotten Realms (as I recall)...or perhaps it was in Magic of Faerun.
Also, there seemed to be a trend towards making psionic versions of a lot of the caster PrCls. If you look at the Spellthief, for instance, you'll see a sidebar detailing the Psi-thief. There are also psionic versions of the Mystic Theurge archetype. IMHO, you can probably tweek just about any arcane PrCl into a Psionic one, and most divine ones would probably work as well.
