The reason I asked about the EO's is because if they are blended or adulterated in anyway, then they could have been the cause of your soap seize. http://www.naturesgardencandles.com/
or brambleberry.com are a good places for EO/FO
Its possible your soap will be fine, sounds like it was at a nice trace before your additions. I would cure it for 6 weeks then test it.
For most of us, a simple recipe is is just a few oils and no additives like egg.
We can help with a simpler recipe but please let us know what oils you have on hand and what oils you are unwilling to use. You will get many suggestions for lard. Many, myself included, feel lard makes a superior soap but some people are unwilling to use animal fats in soap. It would also be useful to know what kind of skin you have (dry, oily, sensitive, etc..)
SB= stick blender
EO= essential oil
FO= Fragrance oil
CO= coconut oil

when beginning, you should make smaller batches. I generally stick to 2 lbs, thats the amount of oils used not the total weight. This is my favorite recipe, makes a nice hard bar with creamy lather. The high amount of lard will slow trace so don't freak out if it takes awhile to get there.
lard 16 oz
Olive oil 8 oz
coconut oil 6.40 oz
water 8.90 oz
