Love the Thrallherd, one of the best flavor PrC in the game.
Simply substituting the additional 'powers' for spells and using appropriate levels for those spells. Burning higher level spell slots for the 'augmented' spells. The Thrallherd gains abilities to drop increased costs for augmentation this is simply treated the same concerning spell levels.
The conversion equation for power points to spell level is as follows.
Spell Lvl=(PP Cost*2)-1
So level 1 would be a 1 PP power and lvl 9 would be a 17 pp Power. Augmentations would be treated in such a way that +2 PP is equal to +1 Level for spells acting linearly (+4 pp would be +2 spell levels)
Other than changing the names of the 'powers/spells' to make it sound like it's coming from the enchantment school rather than the telepathy discipline. The PrC transfers quite nicely from Psionics to Magic because a lot of the abilities in the enchantment/telepathy sections are very similar.
Do to the nature of Psionics though I would highly recommend that you chose a spontaneous caster over the prepared ones because of the level augmentation.
