Our Sunday Visitor has a little green booklet that lists the readings for every Sunday, with CCC citations on the various doctrinal topics these scriptures apply to. I think it is Opening the Scripture or something similar. Use that along with their RCIA catechist guide Making Disciples, which gives you an outline on how to present each topic, and in your plan make sure you cover all the essential doctrine. Along with a guide to the readings by a reliable publisher–we use At Home with the Word because it comes in Spanish and English, some catechists prefer the one from Liguori that goes with their Journey of Faith series–you will be in business. Just make sure that every time the readings say something about baptism, for instance, you don’t re-teach baptism every time, but make sure other relevant topics are also covered.
Several publishers have lectionary teaching guides for children as well, with reproducible worksheets and activities. warning lectionary based catechesis requires more planning to make sure all the content is covered, and it really only works if year round, otherwise you miss one third to one half the readings. This is hard to do with children.
