I use shimano 324. They have an SPD on one side but look like regular pedals on the other. Designed for mountain biking so you can clip out during tricky bits.
I used these when I started commuting but find they are excellent for touring too. Trying to clip in when starting halfway up a steep hill is no fun!
I have a pair of shimano shoes which are not quite as comfy as sneakers but do have a nice flat sole. Pedals are weighted so they always hang the same way. They work great.
