A lot of places will require you to go back to school and get a degree, certification, or at least a lot of credits in education.

For example, the state of Georgia gives this option: "Qualify for a non-renewable certificate and seek employment now, then complete a certification program later: If you already have a bachelor’s degree, you may be able to qualify for an Induction Pathway 4 certificate. This is a 3-year, non-renewable certificate that allows you to teach while you complete a certification program. This certificate can only be issued once you are hired to teach in a Georgia school."

So it's difficult unless you have a degree in teaching. You'll have to go back to school to qualify. And it'll definitely pay less than an engineering job in industry.
