I’d leave aside the paprika, onions & ginger.
Cup of lentils, wash well, bring to boil in plenty of water, clean off the scum that’ll rise to the surface then add a good half teaspoon of tumeric. When the lentils are cooked add some salt & the tarka.
Given what you have there i’d use the following tarka …
Heat a small iron frying pan or saucepan & add a couple of tablespoons of oil. Test the oil heat with a few cumin seeds. When they sizzle, add a teaspoon & a half of cumin seeds. If the chillies are dried red ones, add those now. Fry until the cumin darkens. If the chillies are fresh green ones, add a couple of those with lengthwise slits in them now. (If you have any red chilli powder, half a teaspoon of that goes well here). After 30 secs or so, add 3 cloves of finely chopped garlic & fry until that lightly browns. Pour contents of pan onto lentils & cover for 5 mins.
