Unless you have a suitable alignment tool, this is usually something you need to get your local bike shop to check and fix. That said there are ways of doing it without a proper tool, e.g. using a spare wheel by screwing the axle into the dropout, and then using the spare wheel to check for alignment (parallel to the existing wheel) and to re-align/bend the dropout if necessary.

If it is a removable hanger and you don't have a suitable tool, a good quick way to check is to fit a new derailleur hanger and see if that makes a difference: if it does, that is a good indication that that is the problem. It's always advisable to have a spare derailleur hanger anyway. Incidentally, I think a lot of bike shop mechanics report that even a new hanger might not give perfect shifting, and might need fine tuning when installed.

Thanks, slowster. I've checked the hanger and it looks okay. I'll give it a more thorough check over when I get a chance.
Cheers.

I had to take the wheel off to fix a puncture, so used the opportunity to give the cassette a thorough clean. Also cleaned up around the hanger, jockey wheels, etc. That seems to have cured it!
