How do I cook Cajun fajitas at home?

I need a starting point for a recipe that I can cook at home, but ideally is mall food-court quality at worst or restaurant quality at best. I would try a Cajun recipe first and a Tex Mex recipe, as well. How long does a New York steak bake in an oven at 350 degrees? My problem is that I want to flour-coat the meat. I am looking for any good solutions.
