Could anyone refer a book of Esperanto vocabulary in which the words are classified by themes, rather than alphabetic order; something like Andrey Taranov's series books, or Barron's series?

There is the "bildvortaro" (dictionary of images) in which the words are explained only using images, and they are classified by themes.
You can get it for free online, for example from here.
Ekzistas bildvortaro de Esperanto, en kiu ĉiuj vortoj estas eksplikitaj nur per bildoj kaj grupitaj laŭ temoj.
Oni povas ĝin akiri senpage de la Interreto, ekzemple de ĉi tie.
For everyday words, you might like to try «Mil unuaj vortaj en esperanto». It’s mainly for kids but I think it could be useful for everyone. Each page is a picture of a scene from everyday life and around the edges there are the names of everything in the picture. It’s available to buy from the EAB.
ReVo has the option of selecting any one of the specialties ('Fakoj'), and it then gives you the vocabulary for that specialty.
