You can engage in formal prayer, which includes things like the Rosary, Novenas, the Our Father, and the many prayers officially endorsed by the Church.
You can also, and should, engage in personal prayer. Just tell God what you want in life and ask for help in directing your life towards God and living virtuously. You don't need to deliver flawless oratory, just speak from your heart, however awkward it may sound.
There's also Lectio Divina, a Catholic form of meditating and praying while reading the Bible. The wiki article explains it better and in more detail than I could here:
