The usual restaurant spices are ground coriander, turmeric, cumin, curry powder, paprika, chilli, garam masala. Chilli and paprika are best not kept for too long, the others keep reasonably well as long as they are sealed {keep moisture out}, kept fairly cool and preferably in the dark. {UV light is bad news with most perishables} Old, stale chilli and paprika can taint your curry. Very old curry powder is probably best avoided.
