The infinitive verb to read
I know leer means to read. What process do we go through to get "leyendo"? Also, what is the name of the conjunction?

If you are not interested in grammatical terminology, ignore this post, but otherwise, I'm going to have to disagree with all the posts here so far:
"Leyendo" is what in Spanish call "gerundio", and its closest equivalent in English is the "present participle", like in "I am reading", where "reading" is a present participle.
The "gerund", which looks identical to the present participle, is like a noun, which is what you get in "Reading is good". In these cases, either there is no equivalent in Spanish, or the infinitive is used instead. There is no such thing as a gerund in Spanish.
If you are not sure how to recognize a gerund, replace it with "that" (or any other pronoun), and if the sentence still more or less the same, it is a gerund: "Reading is good" -> "That is good". Notice that it doesn't work with the present participle: "I am reading" -> "I am that".
No wonder we get so many threads where people are confused about "gerunds".
Leyendo is the gerund of the verb leer. Spanish gerunds in present progressive always go with Estar.
Estoy Leyendo el libro = I'm reading the book.
Leer to Leyendo
In -ir and -er verbs, if the last letter in the stem is a vowel, the 'i' in the suffix -iendo becomes a 'y'. e.g.
Leer -> stem = le --> le + iendo ---> 'i' replaced by 'y' = leyendo.
Caer ---> ca + iendo --'y'--> cayendo
Traer ----> tra + iendo --'y'--> trayendo
"Leyendo" is the "gerundio" form (-ing) of the verb "leer". Gerundios are used in the progressive tense.
Estoy leyendo - I am reading.
Estaba leyendo cuando llegaste - I was reading when you arrived.
The progressive tense is formed by "estar + gerundio"...(that is, any form of estar with the gerundio form of any verb)
