Well, it is very likely a simple 120VAC to either 9 or 18VAC transformer, probably rated for around 200-400mA. Any small PCB mount transformer that fits the board ( or that can fit in the space there if you have to do some drilling of new pin holes and make some wire links) will probably work. 9VAC if the relay is a 12V unit, or 18VAC if it is a 24V one.

Can't say the transformer actually looks smoked.  Appears to be some flashover at the line voltage terminals and MOV.  Have you figured out the root cause for the transformer failure or are you replacing just what looks bad?
