I had a BA already in art and had a career in commercial art for 24 years.
Every state has different requirements.
The best thing for you to do is contact your state board that regulates teacher certification. Here in Georgia, they determined I could teach on a temporary 3-year certificate if I could pass the Praxis II exam in art, which I did. Then I had to get required course work done for certification from a college. A job opening became available before I finished course work. I am now teaching and will have everything done for full certification this summer.
