For Abyssal, I would look at the existing rulebook powers and take a selection of powerful spells, and then boost their area of effect/damage.

For Warp Conduit, you can do anything really. I recommend that on a roll of a double for the psychic test, you take perils. A good power would be one that creates a portal that constantly spawns Daemons, like a larger version of the Portalglyph from the Daemons codex. It be pretty cool and balanced, whilst still powerful. You could also look at the existing Apocalypse strategems and tailor some effects to be 'Chaotic' and them use them as psychic powers.

Uber warpflame weapon that uses the Hellstorm template would make for an awesome psychic power too.
