You can use some liquid olive oil soap and EO's. You can try Dr. Bronner's liquid castile (olive oil) soap, or some other olive oil soap, even water and soap flakes will do. If you don't have access to olive oil soap flakes (you can buy them online from soapmakers), you can grate a natural soap bar and heat it, and add some clean distilled water. Some jojoba or olive oil would be good to add something moisturizing to your body wash. You can even add aloe.
As for EO's, you can see what would be good for your particular skin type:
