The Essential Foaling Kit for the First-Time Mare Owner

 towelettes are convenient as well. If your mare is foaling while it's still cold out, consider filling a thermos with boiling water before you go out. It just wouldn't be a proper delivery if someone doesn't get to boil the water, would it? Besides, during long hours at the barn, it's awfully nice having some warm water to wash up with!

Flashlight, Lantern, or Headlamp

Although mares can and occasionally do foal during broad daylight, the vast majority will foal after dark. If you do not have the luxury of a lighted barn, keep a flashlight or a headlamp in your kit. I couldn't get by without my own headlamps. Make sure you have checked the batteries in advance or toss a couple of spares into the bucket.

In addition to the flashlights and headlamps, I rely on a battery-operated lantern (basically a camping lantern) around my barn. It will light a larger area, hands-free, if necessary.

Notebook, Permanent Marker or Pen

Since there's a timeline during which normal foalings proceed, and

 specific time frames during which the foal should be standing, nursing, and passing meconium, it's a good idea to take notes of each milestone. You may be tired from lack of sleep or you may be excited, but don't rely on your memory. Your vet will also appreciate it if you can tell her exactly what time various events occurred.

Should the delivery or aftermath turn problematic, you will also want to advise your vet of key information such as temperature, heart rate, and so forth.

I recommend a fine-point Sharpie™-type marker. It won't smudge or run if your paper gets wet.
