Great question, I always opt out of war if I am missing my offensive weapons. Since you are already in the war the possible methods decress for solid 3 star attacks without your queen and upgraded troops. Depending on your opponents base you can still possibly pull out 3 star attacks and some great 2 star attacks. If you are good with LaLoon attacks and you have hounds that may be method you might want to use. You will need to see how the enemies queen is set, the air defense location, and what the cc is to perform loon attacks. I would suggest if you only want to get 2 stars and you want to play it safe you might want to use a gowiwipe combination. I don't usually suggest ground attacks since I focus on TH9 3 star attacks, but in your senerio a solid ground attack might be your best choice.
This is a little video I did awhile back on ground attacks.
