Surely a big help is a good option download program ( I use Opvue6 ) which gives you the whole option chains in horizontal ( all months ) and vertical ( all strike ) ways.
It takes some experience to see that, but after time it goes better and better.
During the day, when all prices are moving, it is to difficult.
After market closing, or better before market opening, you check the latest prices and compare them from strike to strike and from month to month.
Concentrate only on one market, so you get a feeling for that with the time.
I do that with option on futures. Do not ask me about option on stocks. Never traded them.
IMO it is not useful for your kind of trading. It makes sense, when implementing strategies, where you leg in and out.
You do credit spreads on the Nifty and you do not need that. Even not sure if you would get so much options prices to do such stuff.
Take care
