I cannot find that for you. 

The closest I can find is on cfbstats.com. 

There if you click on any team, you get a list of possible stats. 
Both rushing offense and passing offense have a link for "situational stats" which give you info by down. 
If you also look at numbers of passing and rushing attempts, you can put together a total yds/play on each down. 
That would require you to do a little work, and to compare teams you'd have to step through each team individually. 

I'll be interested to see if somebody has a better site to recommend.
