Get a teacher to get you started. Even if only in the beginning. It will be worth every penny if this is what you truly wish to do. Or get a friend who plays and play for them and let them suggest to you what your course of action might be.
If you can't do either of these things, then get a book and start a lesson plan you are going to be faithful to. The hardest thing for most adult students to do, especially without a teacher is to be disciplined about what they are doing.
Based on what you said in your post , which really isn't much, so I'm mostly guessing in the dark, try this to start. First 5 minutes of warming up your hands. Perhaps a very slow Hanon exercise. If you know your scales, then one octave only , one hand at a time, try a C scale and listen for the control of your fingers. NO speed, but much control. Add to that a few easy pieces of music , where you can be musical. Wish I could say more , but this is like a doctor diagnosing without meeting the patient. Good luck in your studies.
