A few things:
-- Prayer. If you want to know someone, talk with them. Of course, prayer often feels like you're talking to the ceiling, and that doesn't help you to know God or Jesus. But it does indicate a willingness on your part to talk, and sometime God may decide to respond, which leads to the next point.
-- Personal revelation. God may choose to reveal himself to you, which is really a great way to get to know him. Pay attention to what he says or does, and write it down for pondering later.
-- Listen to other peoples' testimonies. Other people get communications from God, too, and share them in fast and testimony meetings.
-- Follow Jesus' example. By imitating him and doing what he did, that can help you know him better in a big way.
-- Read Moroni chapter 7. Whatever persuades you to do good is from God, and that is a clue as to how you can follow Jesus and get to know him better.
Peace, and good luck with your quest to know Jesus better!
