How do you render a normal looking block within a custom renderer? The renderer changes depending on different factors but sometimes it should look like a regular block, how do I do this without just drawing 6 separate squares with tessalator (it doesn't look right when you do that).

You mean like

 

renderer.renderBlockUsingTexture(Block.stone, x, y, z, textureIcon);

If you want to get fancy you can even use

RenderBlocks render = new RenderBlocks(te.worldObj);

render.renderBlockAsItem(Block.dirt, 0, te.brightness());

Do not create a new renderer, one is passed to you for all special renderers.  Creating a new one will likely give you an "already tesselating" error.

Okay I don't think I was very clear. Here is my renderer file.

 

package flayr.lensoftruth.tileentities;

import i.will.skip.the.imports

public class InvisibleBlockRenderer extends TileEntitySpecialRenderer{
@SideOnly(Side.CLIENT)
    public void renderTileEntityAt(TileEntity tileentity, double x, double y, double z, float f) {

	ItemStack heldItem = Minecraft.getMinecraft().thePlayer.getHeldItem();
   	        ItemStack lens = new ItemStack(LensOfTruth.truthLens);
	if (heldItem != null && ItemStack.areItemStacksEqual(heldItem, lens)) {

	ResourceLocation rl = new ResourceLocation("lensoftruth:textures/blocks/invisibleBlock.png");
	Minecraft.getMinecraft().renderEngine.bindTexture(rl);

Tessellator tessellator = Tessellator.instance;
        GL11.glPushMatrix();
        GL11.glTranslated(x, y, z);
        GL11.glNormal3f(0.0F, 10.0F, 0.0F);
        
// Rendering Code        

        GL11.glPopMatrix();
	}
}
}

I have already made a version that used tessalator to individually render all six sides when truthLens is held, however the result looks strange(textures glitch a bit on movement) and it also does not seem like the overall best option. Is there a way to access the regular block rendering code instead?

If you're trying to render a standard cube, use an ISimpleBlockRenderingHandler not a TileEntitySpecialRenderer
