With your kind of background something like the ISACA Certified Information Systems Auditor (CISA) sounds like a perfect target. It will let you draw on your knowledge of audit and accounting procedures to help people use IT technology properly and responsibly. It also offers potential tie-ins to information security work, which is as close to a growth market as opportunities come in the otherwise depressed IT field these days.
Beyond these two specific recommendations, I'd urge you to read some IT trade magazines (InfoWorld, Network World, CIO and so forth) to get a sense of what kind of work IT professionals do. Given that you must understand money and financing, you might even be able to get work in large corporate IT departments by helping them figure out how best to spend their technology dollars.
