yeastless bread help!
Yeast raised doughs, and quickbreads (chemically leavened doughs) have very different basic chemistries (see the answers to the linked reference question for much more detail).

You cannot simply convert one into the other.

I suggest you search for breads designed to be quickbreads, such as Irish Soda bread.
