We don't have to provide replacements for each power. We can just capture a similar theme.
So, how about...
Soell-Like Abilities: At will—blur, lesser confusion (DC 14); 3/day—confusion (DC 17), invisibility (self only), vampiric touch; 1/day—greater invisibility (self only), spell resistance. Caster level 7th. The save DCs are Charisma-based.
Mind blast usually takes the place of psionic blast, but is generally only used on illithid-related creatures. Borrow it, or leave it off?
We'll also need to replace Autohypnosis ranks and Rapid Metabolism.
