Hi Kelsey,
I'm going to assume that you have a DR plan in place and your request is more about the vendors action itself. As you are probably running into, these plans, if done right can be a bit lengthy and it can take some time to get a solid set together. Although I do like capturing such data in an excel database, I managed to find an outline from a while back. It is high level, but it should help you get the ball rolling. Good luck.
