Your local Reference Library should have a Diocesan Directory, which lists all the parishes in your diocese and the priests who work in them.
It is possible that your priest is not affiliated to a local parish, but if in doubt, find out who your bishop is - he is effectively the 'boss' and write to him expressing your concerns about the priest's conduct.
Be aware, the shortage of priests is so acute now, that they'd take gary Gilmore if he wore a dog collar, so a lot of obvious bad behaviour is 'overlooked' by the hierarchy.
It's still worth investigating though.
If you fel able - and I know how much a born-and-bred Catholic can be in awe of a priest - why not go and see him and have a chat about his attitude and approach? It does them good to be given a shake now and again, they live revered lives and it makes them behave badly a lot of the time.
