This is an old proverb seeking its roots in classical latin. According to Neal R. Norrick idioms like that need expansion first then you could examine them based on today's syntactic structures.
Many proverbs such as Like father, like son and The nearer the bone, the sweeter, the meat adhere to formulas, here like X, like Y and The X-er, the Y-er, which do not conform to customary NP + VP syntactic structure...This suggests a cognitive procedure in which a person constructs a complete paraphrase of the elliptical proverb, then assigns the interpretation derived from the paraphrase.
To put it in a nutshell, they're idiomatic expressions that are not subject to conventional grammatical rules of English.
About the part of speech, since the underlying structure is 'Y is like X', according to Norrick, and like is a preposition here, we could generalize it to both like s and consider them prepositins, because like father, like son is a classic example of a parallel structure which demands the same structure on each side. So we have two prepositional phrases in this idiomatic expression.

The word "like" in the proverb presented is a preposition; you use it to express similarity in certain proverbs. Another example:
Like mother, like daughter.
I agree with @Yuri's answer, but the word like in this idiomatic sentence could also be interpreted as an adverb.
There is an implied subject and the sentence is composed of two parallel adverbial phrases:
[somebody's son does things] like [their] father, [and his father does things] like [that] son.
[somebody's son is] like [their] father, [and his father is] like [that] son.
The word like is modifying the implied verbs to do or to be.
