Congrats on the first lucid dream!
Do you have dream goal list of what to do in the dream? If you don't, make one, it's much better to have one and go through it from time to time and already knowing what to do once lucid, than using your lucid time for thinking something up, you can also type/write the most important goals of the moment before going to sleep and/or use them as mantra to increase chance of remembering them in the dream.
Also this tutorial: Dream Control Tutorial - Lucid Dreaming - Dream Views , has some information regarding dream control, check it out.
Good luck with your next lucid dream!
