Initially, my team started by sitting around talking about work item by work item and other miscellaneous topics. Most of the time, this was cathartic but didn't lead to much change.
Recently, we've had a facilitator lead us through activities to drive toward 1-2 actionable outputs to work on for the next sprint. This focus has helped the team actually improve things with our process.
We've been using http://plans-for-retrospectives.com/ for ideas of the activities. A number of our Agile Coaches have recommended the "Agile Retrospectives: Making Good Teams Great" book (but I haven't read it myself).
