All you've got to really do is crap on about how Yeats' poetry is a reflection of his own life. It's best to pick three poems each from the so called different periods of his poetry along with their alternate readings to show how his poetry is a reflection of his life and that the poetry has no meaning when it is taken out of context.
Sorry, but I think you'll find anybody well-versed in classical literature would tear you down if you went around saying that Yeats' poetry cannot meaningfully exist independently of knowledge of Yeats' life.
Take one look at Wild Swans at Coole to see how that statement makes no sense. The dominant reading in that poem is the lyric reading! In fact, I'd posit that the biographical reading actually trivialises the poem as it turns big universal ideas and questions into personal insecurities.
Or simply take a look at the Second Coming - which is entirely removed from his personal life (though the occult remains, knowledge of it is not crucial to deriving meaningful reading from the poem).
You do have something when you mention that his poetry is some sort of reflection of his life, but that's concept that would require careful manipulation if it is to be done correctly.
Heart: Well... that's a difficult question to answer. I guess just think of the different ways to interpret a poem. You can just read it straight off the page, you can try and see if there's any connection to the poet's life, you can try and find references to pop culture or history, you can examine it based on modernism or symbolism (two things Yeats experimented with), et cetera.
With each of these, what to do is partially intuitive. For the lyric reading, look at the nitty gritty bones of the poem: rhyme, imagery, connotations, tense, voice, et cetera. For a biographical reading, examine how knowledge of the poet's life changes or adds to your understanding of the poem, or gives you a new way to interpret it. I haven't covered the historical, symbolist or modernist readings yet, but for the historical at least, the process would be very similar to the biographical reading.
