Shaarei Halacha by R’ Greenwald is very good, and often mentions the Sephardic practice when it differs from the Ashkenazi.
The Ben Ish Chai wrote his own Sephardic book of practical halachah but I’m not sure if it’s been translated.
Meam Loez is very lengthy and focused to a large degree on midrashim, but it is also full of practical halacha from a Sephardic perspective, and has been translated into English by R’ Aryeh Kaplan and others.
