Unfortunately, there is little in the way of dedicated workbooks for grammar like books in the "Practice Makes Perfect" series (e.g. "Practice Makes Perfect Spanish Pronouns and Prepositions", "Practice Makes Perfect French Past-Tense Verbs Up Close"). The most similar workbook that's available for Hungarian is "Gyakorló magyar nyelvtan" which is a grammar reference manual with the grammatical characteristics described in the page on the left supplemented by a few drills in the adjacent page on the right. It's rather expensive for what it is since you will very likely wish that the authors would have offered more than just one page's worth of exercises to complement whatever grammatical point they describe.
A roundabout way to get a reference list of "vonzatos igék" or the required case governance of verbs without paying a cent is to consult a list of phrasal verbs in English for Hungarian students (look for "vonzatos ige angol" on Google). The translations to Hungarian often correspond to a "vonzatos ige". A few lists include this one by angolozz.hu, this one of prefixed verbs by Hunlang or this one by Wikiszótár.
If you buy this book (latest and unused version is only 16 dollars) you will find the perfect explanation to all of the Spanish pronouns.
