Early on I learned a model of prayer that has helped me a lot, using the acronym. ACTS (below). I also find it very humbling and powerful to use Scripture in prayer, using His own words to praise and extol Him; and as if to "remind" God of His promises.

Adoration - every prayer should start with this, addressing the Almighty with reverent awe. It should also conclude with adoration.

Confession - of my own sins, calling then what God calls them - rebellion against the Thrice-holy Creator and Master of all that is. I confess my weaknesses and failings and unworthiness, but I also confess my faith in His provision and power and faithfulness.

Thanksgiving to Him for Christ, for His word and indwelling Spirit, for the Church and its shelter and discipline; for/in whatever circumstances I find myself, knowing that He has brought me there for a purpose that is glory to Him and good to me.

Supplication, first for His work on the earth and close to home, for my country, family, friends, and my own needs.

Again, I think it's important to use Scripture in prayer. It helps me avoid frivolity and distraction, and applies greater true faith to my prayers as well.
