In the appendix of Church Planting is for Wimps, Mike McKinley includes a discipleship training outline from Grace Community Church in Ashburn Virginia.  The outline includes a good list of focused readings and key memory verses and could serve as a starting point for you to develop one for your church or follow on your own.  Much of the reading comes from Wayne Grudem’s book on Bible Doctrine, which is an abbreviated version of his Systematic Theology.  Where links were available to free resources, they’re included below.  The formatting isn’t very good, so you can find a pdf with the same material here.
