The word itself has only one spelling (it is Old Norse in origin) but there are various other words based on it.
The plural is SKIES - like all words ending in consonant +"y", the plural is "ies" (like baby/ babies etc.)
In sport it can also be a verb: "to sky" a ball is to hit it very high (in cricket) and then the past tense would be "skied" , which looks exactly like the past of the verb "to ski."
On the other hand, the rarely used adjective is spelled "skyey" (eg "Let's make that blue a bit darker -it's too skyey") and the nagative adjective, again very rare, is "skyless."
The various words which use sky as a prefix keep the same spelling, whether or not they are written as one word: skylark, skydiving, sky-high etc.
