Prayer meetings are often are characterized by a routine that can become very predictable–and perhaps a little boring. Here is a nearly 400 page handbook that can help with ideas to vary the focus of corporate prayer times (www.prayermeetings.org).
Kress does not necessarily recommend everything on the site or even in the prayer meeting handbook that is linked above–but there are significant portions that can be used in preparing to lead or think about corporate prayer.
May God bless you as you seek His glory in your prayer gatherings.
