I like to take multiple layers of pads and place them separately in the stereo field as well, set the lfo's and what not to slightly different timing/settings so the spaced layers modulate differently. also, break up chords across the layers (i.e. root, third, seventh on one side, fifth and root octave up on the other or something like that)
also - take two different long reverbs that are kind of similar, pan them wide, send pads to both of them to create extra lush reverbs.
also, check out modulated reverbs. i just made a post with a link to some free impulse responses for convolution reverbs - viewtopic.php?f=11&t=9296 - there are some eventide h3000 impulse responses for modulated and warped reverbs that sound great and can make almost any sound a pad if used with a heavy hand.
also. try an expander to emphasize modulation and what not in the pads before reverbs to add some life if the reverbs are sounding too static.
