I would spread out the deck face down. And pull a card I feel drawn to. If it is right side up, it is a yes. If it is reversed, it is a no. Then you look at the card's image to figure out the reason for why. If you get a reversed image for no, flip it right side up to figure out the reason why first.
This is the method I was taught and have seen several professional readers use the same technique.
It is simple, if you understand what the card means(positive or negative association) and/or how it relates the the question, you will be able to derive whether the answer is a yes or a no. I have had much success doing simple yes or no readings with my deck. I generally do a one card reading as I find it more insightful to look at the card's significance in regards to the bigger picture sometimes.
Good luck to you with your future readings.
