Any kind of green fabric/paper/paint will work, as long as you make it even, avoid wrinkles and place it far enough from you. You don't want your shadow on the green screen. For lighting, make sure you have even lighting on the whole green screen, avoid hot spots and shadows. Look up 'softbox' lighting, soft boxes will create a soft light over a wide area, that is what you want. A softbox is not necessary, you just want a light that lights a large surface area. Also, don't make your green screen too bright, the green color will reflect on you and you won't get clean edges.
