There is TEMP_SPACE_ALLOCATED column in V$ACTIVE_SESSION_HISTORY (11g+) that you can use to find out what session uses excessive temp space. Make sure you have the appropriate licenses for using V$ACTIVE_SESSION_HISTORY view.
Creating a monitor for temp space could be a bit challenging because a "bad" query can consume lots of temp space in a very short period of time. You need frequent sampling interval and fast reflexes (assuming there would be human involvement) to make it work.

Subject: limit temp usage before error or out of space condition?
Does anyone have any ideas how to limit temp usage before the query at hand fills up the temp tablespace and then suspends everyone else until the condition is cleared? Is there a way to monitor queries that are using too much temp and send an email? Maybe in OEM? Thanks for your thoughts,
Josh C.
