How does one find lazyness bottlenecks?

Now that ghc 4.08 has a time profiler, I've been improving a program
I wrote over the last year. However now the GC time dominates the
execution time (>60%). I can see that my program is not being lazy,
but I have no idea why. How can I use profiling (or any other means)
to determine where my program is not being sufficiently lazy? Are there
papers on such things I could read?
