I so admire you for sticking to the prey model, bc I know it is so good for them. But maybe, to give her system a rest, you could buy the pre-made raw. The pre-made I use, Natures Variety, already has the organ meat, bone etc. in the meat. It may be easier on her tummy - which at this point, is probably priority.
If the vomiting continues (and diarrhea), I'd do a week of cooked white fish and potato (mashed/cooked), then start over.
