It’s hard to give advice without knowing what you’re doing already and exactly what you find uninteresting or difficult about tefillah, but here are some general things.
1- Talk to God throughout the day. For example, when something goes well, thank Hashem then and there. When something goes wrong ask the ribbono shel olam for help.
2- Look forward to davening. For example, when something comes up that you’re worried about, remind yourself to daven for it “ok, I have to ask for hatzlacha with x at mincha”
3- Know what you’re saying, especially the long parts that people read to themselves. Rav Soloveichik used to describe different parts of tefilla as music with the different aspects of a Jew’s relationship with God as harmonies. Rav Yaakov Kaminecki used to say that pesukei d’zimra was all the mussar seder he needed for the day. Those last two thoughts in particular should help.
