When it comes to modifying ambient light, it's hard to find something easier to use than a reflector. It is the most basic tool for shaping light and it's also the lightest one. I recommend most photographers have at least one in their bag. You never really know when you're going to need it.

But what can you do when you're already at the location and you realize you forgot your reflector at home? The sunlight is really hard and you just can't make anything work without a reflector. It's one of those times when imagination and improvisation can save the day. There are a couple of very effective solutions you can use for replacing a dedicated reflector. Number one is a windshield sunshade. A lot of people have them in their cars even if they don't use them very much. If you're not one of them, ask around. You're more likely to find one you can borrow than not.
The other solution is to make your own reflector quickly and easily. You can use various materials depending on what size you need it to be, but if you want a nice big reflector, I recommend taking a trip to the local hardware store and buying some bead foam. It's dirt cheap, very light and easy to hold and it will get the job done. It comes in precut sizes or you can just cut out your own size according to your needs.
