You could try Tong lane end equestrian at Tong Village. PM if you want their number. There is also Church View at Coley (nearer to Halifax). The hacking is better round Tong
There are loads of yards around the area, but as you would expect some are loads better than others, and as far as I know the best have waiting lists. Best idea is drive round area you are interested in and then start asking, although there is one on Hall Lane (I think) Northowram which is meant to be very good, and another at Norwood Green.
