I would recommend having the character itself on one side, and designing a grid of information for the other stuff on the backside, making the pronunciations the most prominent elements. I would also include sample compounds that use the character you are studying, to give some context.
The method I'd suggest would be to use the cards by looking at the kanji side first and practice writing the character, and try to use it in a sentence, or just write a compound involving that character. Then flip the card over to confirm it. You could also go the opposite way, looking at the meaning or the pronunciation, then trying to write out the kanji before looking at the other side of the card.
