I have several Orthodox prayer books, but right now I am using the Daily Devotional Guide from the Fellowship of St. James, edited and commentary by Fr. Patrick Reardon (Orthodox priest). It includes psalms, morning and evening prayer, and readings from Scripture to take you through the NT each year (the Gospels a little more often) and the OT every 2 years.
I am also in the process of becoming a Benedictine oblate, since the Western Rite churches have developed an Orthodox Benedictine fellowship. This probably won't change my devotions too much, except for adding a monthly communal prayer session.
