Tan Books has several books on prayer, two I noticed by St. Alphonsus Liguori and St. Francis de Sales.

"The important difference with St. Teresa of Avila is, as a Carmelite, she had a grounding in the Rule of St. Albert, which first and foremost emphasizes Sacred Scripture:
Each one of you is to stay in his own cell or nearby, pondering the Lord's law day and night and keeping watch at his prayers unless attending to some other duty. The Carmelite Rule of St. Albert, Chapter 11"
One could start with the Lord's Prayer, and then from there study every single prayer mentioned in the New Testament. (The Gospel of John is a great place to start, especially with the 'High Priestly Prayer' of Jesus where He was praying in the garden.
One thing also, I agree with so many of the others here who have said that contemplative prayer is NOT 'centering prayer'.
"Be still and wait on the Lord" is NOT getting "in touch with the God within you".
