Depends on whether you prefer canon only or don’t mind non-canon. In the legacy dictionary, mos is the non-canon word for like. But if you wanted to express the idea of liking something in canon vocabulary, here are a few potential options. You could say that something is smoliini, or “my passion.” You could say that the subject of your liking is bahlaan, “worthy.” Or, more simply, you could just say that the thing you like is pruzah, “good.”
