Kicks often can be high pass filtered at 40 hz, high shelf cut around 10 khz, and some sharp cut in the unnecessary low mids around 250-500 hz. Wherever it sounds bad.
Follow that up with a compressor that has >45 ms atk time, and short release around 5-10ms to avoid compression artifacts.
Snares I'll often high pass filter a bit higher, around 100 hz, also typically with some cut in the low mids.
Then a compressor with a short atk and long release to allow the transient of the hit through, while compressing the body to bring it up.
Also be sure to high pass filter your other tracks so they're not muddying up the mix and clouding your drums in the crucial low frequency ranges.
Hope that helps!
