First thing you can do is take the bottom fairing off, clean the leak areas really thoroughly, then see if you can put baby powder or something similar that will stick ok to the areas where you're noticing the leaks. You could probably get a couple more ideas for this by googling how to find leaks in an engine
You need to pinpoint the exact locations of the leaks.
During that fall, there's a good chance a part or parts of the engine suffered cracks, if that's the case then there's not much you can do outside of buying a new engine. I know that's not news you want to hear, and maybe that won't end up being the case. But objective number one needs to be to pinpoint the leaks.
Depending on the age of your bike, you may need to replace the coolant pipe o-ring and gasket, then properly torque all the bolts. The clutch side may require a gasket and also properly torqued bolts. Also do as recommended, locate/isolate the leaks and inspect for possible engine crankcase cracks.
