Narrative:

My student and I were operating under an IFR flight plan on a training flight in his aircraft into ramona; ca (rnm). As the instructor and more experienced pilot; I was acting as pilot in command and; as the pilot not flying; was communicating on the radios as my student flew the aircraft. After receiving our approach clearance for the GPS runway 9 approach into rnm from socal approach; we began our final descent along the approach course of 085 degrees. We had listened to the rnm ATIS; which was reporting a ceiling of 1;300 ft and runway 27 in use; accordingly; we expected a circle-to-land to the south (as circling was not authorized north of runway 9/27) into the left downwind for runway 27. After confirming that we were established inbound; socal approach switched us over to rnm tower; and I reported that we were 'inbound on the GPS 9 approach; circle-to-land to runway 27.' tower instructed us to 'circle south; left downwind for runway 27 at ayoda' fix; which I confirmed in my response. We continued our descent to our circling MDA of 850 ft AGL; and finally broke out into VMC about 1 NM past ayoda. With the airport in sight; we began our right turn into the left downwind for runway 27 at 2;300 ft MSL. As we maneuvered; another pilot in a citabria radioed in to tower that 'aircraft X just missed us. They're right above us now.' to confirm our position for both tower and the other aircraft; I reported that we 'were now on left downwind for runway 27.

Title: Two light aircraft experienced what was described as a NMAC following a failure by the reporter to report a fix prior to circling for landing following a practice GPS approach to RNM.
