Where to Start in Creating an Icon Pack for the Play Store.

So, as a graphic designer, I've been absolutely loving all the customization my android's brought me for the past year & 1/2. I've been creating my own icons for my device now for the past few months, but I've always done it by loading .png files to the sd card and replacing the icons of my homescreen apps with something like Nova, Go Launcher or ADW (I've cycled through a bunch, but have been using Nova steadily for the most part)

I've been wondering lately how feasible it would be to flesh out some of my icons into a full fledged pack/theme for one of these launchers.

So I was just wondering, does anyone have a good place to start where I could learn how to start packaging these things and get them up on the Play Store?
