I'm not fluent, but I'll give it a shot. Fuzion and Snake are our two resident spanish-speakers, so they may be able to help out better than I can.
Yo puse media hora a remojo las lentejas. Mientras yo fui a preparando los ingredientes: yo trocia el jamón en dados pequeños, yo corté el chorizo de guiso en rodajas, yo corté también a rodajas finas las zanahorias y las patatas pequeñas yo pele y yo deje enteras;
(I put in half an hour of time into the lentils. (Mean?)While I was preparing the ingredients: I diced the ham into small pieces, cut the sausage casserole(?) into slices, I even also cut into fine slices the carrots and small potatos left aside;)
Una vez remojadas las lentejas (tras esa media hora) yo puse al fuego en una cazuela que las cubra de agua. Depues yo eche a la cazuela lo que hemos ya preparado: el jamón, el chorizo, las zanahorias y las patatas. También yo eche la hoja de laurel, la pimienta, el azafrán y el vino.
(Once the lentils soaked (for about half an hour), I put then over a fire in a crock with water. Later I threw into the crock everything else that I prepared: the ham, the sausage, the carrots and the potatos. I also threw in a leaf of laurel(?), pepper, saffron, and wine.)
Yo pice la cebolla (cortadita en trozos pequeños) y yo eche a la sartén con el aceite. El ajo yo pice y yo agrege a la cebolla. Yo deje sofreír hasta que yo frie (pero que no se ponga dorada).
(I chopped the onion (cut it into small pieces) and threw it into a frying pan with oil. I chopped the garlic and added it to the onion. I left it to brown until I(?) fried (but not golden).
(Bad subject-verb agreement)Yo agrege la cebolla y el ajo a las lentejas y yo puse la sal en la cazuela que ya estaba al fuego. Tandare de 30 a 40 minutos con un fuego mediano.
(I added the onion and garlic to the lentils and added salt into the crock that was already heated. I let it sit for 30 to 40 minutes over medium fire.)
That's the best I could do. I used a website called freetranslation.com. It's not the best, but it gave me an idea of what you were saying when I didn't know certain words.
Also, if you want to say 'heat,' use 'calor.'
Since this is in the past, make sure all your verbs are past tense, and make sure the Subject-verb agreement is good.
The words with a (?) next to them I was not sure what you were talking about, or I wasn't sure if that's what you meant.
