Simple witchy things I wrote down a long while back for myself:
• Can’t burn candles? Use LED candles instead.
• Don’t have colored candles for specific intentions? Write your intentions on a piece of paper with markers of similar colors. Then put it under your available candle.
• Can’t burn paper for spells? Use water-soluble paper to dissolve in water instead. Or just tear the spell paper up and throw it away.
• Can’t bury things or cast things into a body of water? Just chuck them in the trash.
• Can’t burn incense? Use holy/blessed water in a little spray bottle instead.
My motto for art goes for witchy stuff too: Do what you can with what you have.
