My iPad was just stolen in Mexico, what can I do to locate it?

Unless you had enabled Find My iPad on it before it was stolen then there isn't any way to locate it.

If it was stolen then you should report it to the police. You should also change your iTunes account password, your email account passwords, and any passwords that you'd stored on websites/emails/notes etc.
