The trick is pretty much every book you'll find will discuss fixed- 
cutoff filters - make them voltage controlled is tricky. The  
suggestion someone had of just finding an existing schematic of a  
filter type you like and adapting it is a good one.

I'll also take this moment to plug the appropriate lectures from the  
course I ran last Spring:
