If you are looking for some edifying prayers, try Philip Law's Praying with the Bible (London: SPCK, 2007). The book is divided into six parts: adoration, confession, thanksgiving, petition, intercession, and contemplation. Each prayer is written in simple, contemporary English and is an adaptation of a portion of Scripture. Some would be more suitable for personal use, but most could be used in a corporate setting. This would be a good book to give to new Christians, to teach them how to pray, but it would also be a very helpful resource for those preparing church services or leading prayers.
Another useful book of prayers, edited by C. Micklem, is A Call to Prayer: Public Worship through the Christian Year (Grand Rapids: Eerdmans, 1993). This incorporates material from several earlier publications and includes prayers by seven contributors, which are much more obviously meant for corporate use. Some are topical and others are seasonal. Although they are biblically informed, these prayers are not paraphrases of biblical texts as Philip Law's are.
