Hey Mate,
I found this recipe here somewhere. It was a really nice beer and will make it again. It was close to a Fat Yak, I didn't hit the efficiencies so that may be why it wasn't perfect.
All in all I think it is a good starting point.
It's also been said here that the current Fat Yak that is sold is not as good as the originally brewed beer.
