[AtLA] If Koh stole my spirit's face, what would happen to my physical body?

Without a face, I can't breathe, so would I die while my faceless spirit runs around in the spirit world?

Well, we know a couple things. 

1) Koh is a spirit monster

2) You can still survive without a face in the avatar world. 

We know the first one from the show, and the second from the comics. 

However, we also know that Kuruk’s girlfriend was killed by Koh, so there seem to be multiple possibilities. 

Koh could either steal your face and your soul, or he could steal your face and not your soul. So you come back to the normal world without a face, but are still somehow able to survive.
