We have been doing a letter each day. We practice writing the capital and lowercase letter. We learn the sound with the jolly phonics motion and we come up with a list of words for each letter and then I draw a picture. (Some letters are easier than others, my kangaroo for K was a more of a sad squirrel.)
I've also been creating ABC centers. There is tons of free stuff out there. Search pinterest and TPT to find lots of great resources.
I also just added a new item to my Teachers Pay Teachers site. It's a find the missing letter activity. I plan to use it once my kids get a little bit better at the alphabet.
