Answer
Hi James,
If those lights are on with the light switch off then all you need to do is to take your wiring diagram and start tracing with a test light from the load (light that is on) towards the power supply. Which should have been the light switch but is obviously some other power supply or a bad light switch.
If you don't have a wiring diagram let me know and I will put one on my web site for you to copy.
