If everything you write is sounding like overused tropes and clichés, it may be that you're simply showing your influences. And when you see your writing, all you're seeing are those influences. Hence, it feels less substantial to you.
What, exactly is "bland, generic fantasy" to you? I suggest you define what it is you're trying to avoid. Make a list if you're so inclined, or just get it straight in your mind what you want to sound different from. You could then go ahead and write, specifically avoiding these areas. While this could push you into writing about new and interesting things, it could also be difficult restriction to deal with. What if there's very little left after this process?
All writers have influences. With some, it's more obvious than with others. However, the only cure to this is, unfortunately, to keep writing. Don't stop just because something seems familiar or fake, just note it for future revision. With a little talent and time, your influences will blend into a style that is yours. It won't happen quickly, or without some hard work, but have some faith that it will happen.
You ask for specific methods: Since becoming aware of your influences and stylistic leanings will only help matters, getting some critiques of your work with that in mind may help. However, volume is your friend: Get those pages written. Don't stop if they suck, just keep going. You won't learn from the experience if you don't. Some specific working regimens, if you don't have them, may also be of help here.
