Ethereal jaunt sounds good! In fact, the shedu has it:
Ethereal Jaunt (Su): A shedu can shift from the Ethereal Plane to the Material Plane as a free action, and shift back again as a move action. This ability is otherwise identical with ethereal jaunt (caster level 15th).
The shedu also has this:
Depart (Su): Once per week, a shedu may cast astral projection (caster level 18th). The ability affects only the shedu.
Attack/Defense modes: B, C, D/all
Body Equilibrium, Empathy, Sensitivity to Psychic Impressions, Mind Bar, and Telepathy.
Summarizing...
Ego Whip (2nd, save)
Empty Mind (1st, no save)

Intellect Fortress (4th, no save)
Mind Thrust (1st, save)

For telepathy, I'd suggest we simply give 'em telepathy 60 ft. on the SQ line.
We'll need to figure out usage intervals for the rest.
