My approach would be to create a list of installed rpms for what you're using as the base system:
rpm -qa --qf "%{NAME}\n" | sort > starting.txt
Run that command again when you have all of the extra stuff installed, using a different filename for the output, for example, ending.txt
Now merge and compare those files, and pull out the unique entries:
sort starting.txt ending.txt | uniq -u > newstuff.txt
Now remove the files in newstuff.txt
yum remove `cat newstuff.txt`
There is probably a way to combine those last two steps into one single command.
