I'm going to assume that this is using some sort of dispatch-table mechanism. If it's not, rip it apart and start over. Seriously.

If it's using a dispatch, those globals may be appropriate. Globals aren't necessarily bad. In fact, in a dispatch-table setting, they can actually be very useful.

If you're gung-ho about migrating these functions into a module, I'd look at rebuilding the dispatch with an OO context. How that would happen is very dependent on what exactly you're doing.
