Gas state is generally a term used to describe the elements in gas phase while Vapour is a term used to describe compounds in their gas phase.

For (e.g)
Nitrogen Gas, #NO_2# vapour, #PH_3# vapour, #NH_3# vapour.

Special cases like synthetic gas etc exist. But these are mixtures of compounds in their corresponding gaseous state.

Hence Water vapour is Water in gaseous state.
