Well, in Tagalog there aren't really conjugations like you might be used to in another language.
Tagalog uses a system of affixes; prefixes, infixes (things added to the middle of the word), and suffixes.
It is a highly complex thing to teach, and I don't see a lesson here on Tagalog.com for it.
What I recommend is that you get yourself a grammar book; namely, "Essential Tagalog Grammar" by Fiona De Vos. In there, you will find rules on how to create verbs from root words.
Mag is a complex prefix used in nouns, adjectives, and verbs (it's not always a verb).
However, in terms of verbs, it can be used to express these things about a root word:
1. to do [root word]; focus on doer of the action
2. to take up occupation as [root word]; focus on doer
3. to use or wear [root word]; focus on doer
4. to perform a reciprocal action in relation to [root word]; focus on doer
5. to be [root word]; no focus
6. *to do [root word] repeatedly; focus on doer
7. **to perform a reciprocal action involving >=3 doers in relation to [root word]; focus on doer
8. **to do [root word] occasionally; focus on doer
9. ***to do [root word] together (with someone else); focus on doer
* This affix requires syllable repetition (first syllable of root word repeated), see the example.
** This affix requires double syllable repetition (first two syllables of root word repeated), see the example.
*** This affix requires the "mag" prefix and the "an" suffix.

You can find the grammar book I'm referencing on this page of this site:

However, thankfully, the online version is free. I do much prefer the book version and I implore you to buy it both to support the creators but also because it gives a much better learning experience in my opinion.
However, I digress, the link is here:

Scroll down to mag-1. In this post I walked you through mag-1 through mag-...-an.
