normal soil, nuked is what Stanley Schultz often uses*, and he's been doing this for decades. Peat moss is a good alternative.
Why not just remove some of the vermiculite (especially where the T isn't venturing) and replace with soil or peat, give it a quick stir and it'll be fine. Then just add a little more over the rest of the vermiculite. There's really no reason to take it all out again.
No matter that you didn't come, its waiting for you for the next time I decide to have a meet
*I think I'm right in suggesting that Stan doesn't even bother trying to sterilize his soil and if you think of it the soil in a tarantula's natural habitat is far from sterilized.
