Hey Jim,
I've never seen a tutorial about fire making that is specific to using an AE light but if you just mean, building a fire that reacts to light, I've seen several. Here's one that uses particles.

So, I guess practical fire isn't an option, such as some of the Andrew Kramer stock fire stuff? I know there are a couple of them that look just like a normal camp fire and are real of course.
